When you run a node on a personal device, you can select from a list of known tasks that suit your device type, and then begin staking your KOII tokens in order to fulfill the task responsibilities. Each task contains an Executable, an Audit Function, and a Rewards Model, which can be audited by any user in advance of participation.
Once staked, your node must remain online to fulfill task executions according to the rules of the Audit Function, and will operate in the background on your devices to provide microservices to Koii-X apps and developers.
